STREET-OAR HEATER.

SPECIFICATION forming part of Letters Patent No. 227,345, dated May 11,1880.

Application ilcd January 24, 1880.

To all whom it may concern:

Be it known that I, GEORGE C. BOVEY, of Columbus, Franklin county, Ohio,have invented certain new and useful Improvements in 5 Street-CarHeaters, of which` the following is a specification.

This is an improvement on Letters Patent No. 211,963, granted to myselfand George B. Kerper, February 4, 187 9, for street-car heater;

Io and the present invention consists in constructing the heater in sucha manner as to cause it to occupy less space both underneath and withinthe car or other vehicle, and at the same time all danger of settin gtire to the car is 15 completely obviated.

In the annexed drawings, Figure l is a vertical section through thelower part of a streetcar provided with my heater, a portion of thelatter being broken away and shown in section.

zo Fig. 2 is a vertical section of the heater taken in the plane of thegrate-bars, the magazine and suspension-rods being omitted. Fig. 3 is aplan of the apparatus; and Fig. 4 is a horizontal section ot' the same,the section being z5 taken in the plane of the air-inlets of the hotairchamber and the central portion of the apparatus being broken away.

A B C represent, respectively, portions of the iioor, side, and one seatof a street-car or 3o other passenger-vehicle, a suitable opening beingmade in said floor to admit the heater, which is constructed as follows:

D represents a tire-box having a door, d, grate-bars E, and ash-pit F,which latter can 3 5 be emptied by simply opening a trap, Gr.

Located a suitable distance from box D, and surrounding three sides ofthe same, is a partition or wall, H, whose opposite ends are secured tothe front plate of the heater in the 4o manner shown-in Fig. 4, whilethe upper and lower margins of this partition are attached to ribs orlugs projecting from the top and bottom plates of the lire-box, asrepresented in Figs. l and 2. Furthermore, this partition 45 isfurnished with air-inlets h, which may be made in both of the sides andalso inthe back of the same; or, if preferred, these inlets may take theshape of slots h', as representedin Fig. 4, which slots may be locatednear the 5o front plate of the apparatus, to compel the air to traversea very circuitous route in passing through the heater. The annular spacethus afforded between said partition and tire-box constitutes thehot-air chamber I.

The extreme outer casing or jacket, J, is 55 composed of one or moresheet-metal plates united to the front of the heater in the manner shownin Fig. 4, and securely riveted or bolted at j to the marginal flangesot the top and bottom plates of the tire-box D. This 6o jacket inclosesa space, K, known as the coldair chamber, which chamber has inlets lc ofany sh ape. Said jacket projects some distance above the top plate ofthe heater, as at L, the margins of this extension being bent down at 65 Z, and then nailed or screwed to the car-floor, as shown in Fig. 3.Frvidently this bent portion or liange Z will be sutlicient to hold theheater firmlyl in position, provided the jacket is made oi moderatelythick metal; but in or- 7o der to render the attachment ot' the heatermore secure a number of stirrups or slings or suspension-rods, M, may beemployed, their upper ends being bent down and attached to the tlooratm,whi'le their lower ends,m, grasp 75 the margins of the jacket andthebottom lian ge of the nre-box, as seen in Fig. 1.

It' preferred, the rivets or bolts j', that unite said jacket andiianges, may also pass through these suspension-rods. The re-boX D issnr- 8o mounted with a dome, N, to which is applied a smoke-pipe, O, thelatter being, preferably, carried along underneath the seat C, andthence up at the corner of the car or on the outside of the same, asshown in my old patent. Gast 8 5 with or otherwise applied to this' domeis an inclined chute or magazine, I), having near its lower end a gateor cut-ott', R, whose handle r is to be engaged with a rack, S, or otherdevice capable of maintaining said gate in a suit- 9o able position toregulate the flow of coal from said magazine to the fire-box. T is thecharging-door of this magazine.

Openings U are made in the top plate of the heater immediately over thechamber I, to 9 5 allow the warm air to escape directly into the car.

The dotted lines V (seen in Fig. 2) indicate the position of a shield orguard that may be attached to the oor and seat of the car to pre- :oo

vent the passengers feet or garments coming in contact with the heateddome.

W W represent the customary internal Wheel-guards of a street-car.

By referring to Fig. 2 it will be seen that cold air enters at inlets7c, then descends and passes Vthrough openings It into chamber I, wherethe air becomes heated by contact with fire-box' D before escaping atthe outlets U, as indicated by arrowsin said illustration. Consequentlythis part of the apparatus insures a copious supply of pure warm air tothe car or omnibus or other vehicle to which the heater may be applied,and at the same time heat is radiated from the' dome M and pipe O. Oneadvantage of this -form of heater is that it is located Wholly under oneof the seats, while in my old patent the apparatus is represented asextending completely across the car, and occupies considerable spaceunder both seats. N ow, this old arrangement, besides being complicated,heavy, and expensive, is valso objectionable on account of it being inthe way of the brake attachments on some forms of cars. Furthermore, theold apparatus concentrates too much heat at one place, and is liable toset tire to the straw in the cars; but all of these objections areobviated by the present construction, which affords a cheap, simple, andlight apparatus that is situated wholly underfjeither of the car-seats,and does not in the least interfere with any form of brake attachrnents.

Anotherladvantage is its perfect safety from iire, as the prolongation Lof the external jacket, J, prevents any appreciable degree of heat beingcommunicated from the apparatus to the car-iioor orjto any straw orother covering spread upon the same.

A still further advantage results from the use of magazine P and itsaccessories, as the gate R can be so adjusted as to insure a con-Vtinuous supply of a greater or less quantity of fuel to the firebox D,the vibrations of the car causing a regular iiow of coal down saidinclined chute.

1f preferred, the door T of this chute may be omitted, and the magazinemay be extended up through seat C, as shown at X, a trap -door being` inthis case hinged to the seat, so as to afford facility for charging saidfuel-chamber T. Finally, the dome may be omitted.-

I am aware it is not new to surround the furnace of a car-heater withapartition inolosed by an outer jacket, as such a construction is seenin Letters Patent No. 67,770, issued August 13, 1867, to W. G. Kendrick.Therefore my claim to this feature of the invention is expressly limitedto a street-car heater whose furnace has an external iire-door, anintermediate partition, and an outer jacket, which jacket is carried upa suflicient distance above the furnace or lire-box to prevent heatbeing communicated to the floor of the car, as herein described andillustrated.

I claim as my inventionl. A street-car heater consisting of afurnace, D,having an external tire-door, d, partition H, hot-air chamber I,cold-air chamber K, inlets h 7c, dome N, inclined magazine P T, andventages U, the outer jacket, J, of said cold-air chamber being extendedabove the iire-boX at L and attached to the car-Hoor at l, as hereindescribed, and for the purpose set forth.

2. In combination with a car-heater of the class specified, the outerjacket, J, and suspensionrods M, which rods are attached to the Hoor atm and are secured to the heater by the same bolts or rivets, j, thatunite the jacket to the fire-box, as herein described.

In testimony of which invention I hereunto set my hand.
